The Wallabies star has a history of making anti-LGBT statements and recently made headlines saying gay people were destined for hell "unless they repent of their sins and turn to God".

Apa took to Instagram to label Folau's comments "very disappointing", suggesting his position made him a bad Christian.

Our role as Christians is to love, not judge, What gives you the right to condemn? Are you perfect? Sit down.

Apa is former Shortland Street actor who is well-known internationally as the lead character in US series Riverdale.

Folau, who is married to Silver Ferns star Maria Folau (nee Tuta'ia), was called before Rugby Australia CEO Raelene Castle over his homophobic comments.

"We're proud of the fact that he's a strong believer and he's prepared to stand up for what he believes in," Castle said following the meeting.

It seems unlikely Folau will apologise, however Castle told media the 29-year-old "acknowledged that maybe he could have put a positive spin on that same message and done it in a less disrespectful way".
